Witryna11 kwi 2024 · The construction of all-carbon quaternary centers in small-ring systems is important but challenging in organic synthesis. Herein, by taking gem-difluorocyclopropyl bromides (DFCBs) as a type of general and versatile building block, we developed a practical method for building all-carbon quaternary centers in gem-difluorinated … WitrynaHydrocarbons can be described as organic compounds consisting of two major kinds of atoms — carbons and hydrogen. Generally, these are colourless gases with nearly no odour. Based on their types, hydrocarbons may possess simple or complex structures. Further, these are mainly classified into four major parts: alkenes, alkanes, alkynes, …
Organochlorine chemistry - Wikipedia
A polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two aromatic rings and the three-ring compounds anthracene and phenanthrene. PAHs are uncharged, non-polar and planar. Many are colorless. Many of them are found in coal and in oil deposits, and are also produced by th… Witryna7 gru 1998 · The prototype of a portable fiber-optic sensor system for monitoring apolar hydrocarbons in groundwater or industrial wastewater is presented.
